Abstract: An LDD lateral DMOS transistor is provided in a lightly-doped epitaxial layer (512) of a first conductivity above a substrate (505) of the same conductivity. A highly-doped buried layer (501) of the first conductivity is provided under the LDD lateral DMOS transistor to relieve crowding of electrical equipotential distribution beneath the silicon surface. In one embodiment, a gate plate (511) is provided above the gate (509) and the gate-edge of the drift region. An optional N-well (506) provides further flexibility to shape electric fields beneath the silicon surface. The buried layer (501) can also reduce the electric field in a LDD lateral diode and improves cathode-to-anode reversed-recovery characteristics.

Abstract: A gas chromatography system of the type incorporating a thermal focusing chamber for introducing a sample into a column for separation and analysis. The system of the present invention provides benefits in terms of reducing memory effect of one analysis being influenced by prior experiments, a reduction in system dead volume which leads to broadening of peaks produced on the chromatogram and artifacts caused by sample decomposition. These advantages are achieved principally through a novel fluid circuit in which the sample is trapped onto the column by trapping it at the end of the thermal focusing chamber closest to the column. This feature has the effect of eliminating the necessity of the sample residing in the heated focusing chamber for a period giving rise to sample decomposition. This system further avoids the necessity of passing the inlet flow through mechanical valves which also contributes to memory effect. This system further has the benefit of enabling sampling of sources at various pressures including ambient pressure as an air quality sensing probe. An alternative embodiment is a simplified system for enabling ambient pressure source monitoring without mechanical valves in the sample flow path.

Abstract: A LCD controller/driver utilizes a bi-directional data ring to enable quick and easy data alteration and shifting. The controller/driver couples cascaded segment drivers (32, 34) to a row data serial interface (24) which links the drivers with a control circuit. The cascaded segment drivers coupled to the row data serial interface define the bi-directional data ring. Display data input into the segment drivers may be altered by shifting the data into the data ring and transmitting such data to, or through, other segment drivers and to the row data serial interface, where the data is altered by inputs from the control circuit. The control circuit is further coupled to a horizontal pointer register (64). The horizontal point register has latched, from instructions from the MPU, two locations within the data stream of the data ring. These pointers define the boundaries of the area (active region) to be amended or replaced by the MPU.

Abstract: Method and apparatus for calibrating the drive current circuit of a semiconductor laser diode subject to reflected optical feedback from a target surface such an an optical recording disk. The method makes use of two power output vs. drive current characteristic curves for the laser, one curve 190 for in-focus condition and the other curve 191 for out-of-focus condition, wherein the curves exhibit an asymptotic region at high power level (P2). Measurement of drive current I2 at power level P2 is taken under an out-of-focus condition. Measurement of drive current I1 and I3 at a predetermined low power level P1 are taken for both out-of-focus condition and in-focus condition. The linear slope of the in-focus curve 190 can thus be calculated to set desired power levels.

Abstract: A mask is used for lightly doped drain and halo implants in an integrated circuit device. The mask exposes only portions of the substrate adjacent to field effect transistor gate electrodes. Since the halo implant is made only near the transistor channels, where it performs a useful function, adequate device reliability and performance is obtained. Since the halo implant is masked from those portions of the active regions for which it is not necessary, active region junction capacitances are lowered. Such lowered capacitances result in an improved transistor switching speed. The mask used to define the lightly doped drain and halo implant region can be easily formed from a straight forward combination of already existing gate and active area geometries.

Abstract: For confidently coupling towed external devices (10) to a marine seismic cable (14), a latch mechanism (12) having a novel swing plate (s) to improve the adjustability of the mechanism (12) and provide a positive, clearly visible indication of latched and unlatched conditions. The swing plate (s) serves as an external linkage between a rotatable adjustment head for a locking pin (24) and a translatable lever arm for a locking rod (50). The locking pin (24) and the locking rod (50) extend from a latch housing (12) on a towed device (10), such as a cable-leveling bird, and engage with a keyhole slot (52) in a locking collar (16) on the streamer (14). The swing plate (s) engages the adjusting head, which protrudes from a side of the housing, in a push-nut engagement. Shoulders (70) positioned approximately radially opposite each other on the swing plate (s) push against the lever arm (54), which also protrudes from the side of the housing (12), as the adjustment head is rotated to completely extend or retract the locking rod (50) into the mating slot, thereby locking or unlocking the mechanism as the lever arm is jammed to the top or the bottom of a guide slot (52). As the adjustment head is rotated to force the lever arm to the top or the bottom of the guide slot, a positive stop, which is clearly evident to an operator performing the adjustment, is provided. The structure of the swing plate (s), such as structure along a radial sector of the swing plate between the shoulders (70), is also used to occlude and reveal clearly visible indicia of a locked or unlocked mechanism as the swing plate (s) is rotated.

Abstract: The concentration of a developer for use in developing resists in the fabrication of integrated circuits of semiconductors is adjusted highly accurately using a load cell. A stock developer and pure water are supplied to a mixing tank supported on a load cell, and mixed into a diluted developer in the mixing tank. The concentration of the diluted developer from the mixing tank is analyzed by an automatic analyzer, which then calculates the weight of a stock developer or pure water to be introduced into the mixing tank based on the analyzed concentration in order to achieve a predetermined concentration. Then, either a stock developer or pure water of the calculated weight is supplied to the mixing tank until the weight, as measured by the load cell, of the mixing tank containing the stock developer and the pure water is increased by the calculated weight. 
Thereafter, the diluted developer is transferred from the mixing tank to a reservoir tank.

     A method for operating a polyphase dc motor having a plurality of driving coils is presented. According to the method, drive current supplied to the driving coils is chopped to control the maximum current delivered thereto by turning the drive current on and off. Zero crossings of a back emf voltage of the driving coils that are connected into a floating state are detected for producing a commutation signal, and the detection of zero crossings is inhibited for a predetermined time after the drive current is turned off during the chopping step to avoid detecting a false zero crossing. The chopping is performed as a part of a PWM operation.
